It was a cunning plan. During the night, the four inmates at a prison in Darwin, Australia climbed over the fence, where they met partners on the outside. These colleagues gave them alcohol and marijuana. After partaking of those refreshments for a few hours, the prisoners climbed back over the fence and got back into their cells, hoping they wouldn't get caught.

Then they repeated the process a few times.

Finally, early on the morning of July 20, guards noticed these thoroughly drunk prisoners in the yard, fighting over a cell phone. They have since been transferred to a higher security unit. Authorities are not sure if the four will be charged with attempting to escape from prison.
